 Paxcounter can be used to sync a wall clock which has a DCF77 or IF482 time telegram input. Set *#define HAS_IF482* or *#define HAS_DCF77* in board's hal file to setup clock controller. Use case of this function is to integrate paxcounter and clock. Accurary of the synthetic DCF77 signal depends on accuracy of on board's time base, see above.

 This describes how to set up a mobile PaxCounter: Follow all steps so far for preparing the device, selecting the packed payload format. In `paxcounter.conf` set PAYLOAD_OPENSENSEBOX to 1. Register a new sensebox on https://opensensemap.org/. In the sensor configuration select "TheThingsNetwork" and set decoding profile to "LoRa serialization". Enter your TTN Application and Device ID. Setup decoding option using `[{"decoder":"latLng"},{"decoder":"uint16",sensor_id":"yoursensorid"}]`
